IMPROVEMENT IN ROCKING-CHAIRS.

Specification forming part of Letters Patent No. 217,625, dated July 15, 1879; application filed May 12, 1879.

To all whom it may concern:

Be it known that I, WILLIAM LIESENBEIN, of the city, county, and State of New York, have invented certain new and useful Improvements in Rocking-Chairs, of which the following is a specification.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved rocking-chair; and Figs. 2 and 3 are, respectively, a vertical transverse section and a side View of the base and seat connecting mechanism, shown on an enlarged scale.

Similar letters of reference indicate corresponding parts.

This invention relates to animproved rocking-chair of t] at class that is popularly known as patent robK-rfls, and the invention 0011- sists of a rocking-chair the supporting-base of which is provided at both sides with curved guide-plates, that are attached to the rails of the same below the level of the top of the rails. The rockers of the seat-frame are connected by downwardlyextending arms and strong spiral springs with the guide-plates, the arms having solid U-shaped cheeks that work between the hook-shaped terminals of the guide-plates. At the lower ends of the arms are arranged inwardly-projecting stoppins, with cushioning rubber rollers or sleeves, that are engaged by the hook-shaped ends of the guide-plates.

One of the most disagreeable features of a large number of the so-called patent rockers consists in the lifting out or disconnecting of the guiding devices, so that the seat-frame becomes locked when arriving at the extreme end of its rocking motion.

Another objection to these rocking-chairs is, that the cushioning-sleeves of the stop-pins become detached and lost, so as to produce the noisy and unpleasant working of the chair.

These defects I have intended to avoid by my construction, by which the smooth and reliable rocking of the chair is secured by a strong, simple, and durable mechanism that is quickly applied to the chair, and then directly ready for work, without recessing the rails of the base-frame or of the rockers.

By referring to the drawings, A represents the base or supporting frame, and B the seatframe, of my improved rocking-chair. To the inner sides of the horizontal rails of the baseframe, on which the rockers of the seat-frame swing, are screwed curved or U-shaped guideplates 0, the upper ends of which are turned inwardly, so as to form hook-shaped terminals. The guide-plates 0 do not project above the rails of the base-frame, but are attached so as to be entirely below the top level of the same, as is clearly shown in Figs. 1 and 3. From the lower portion of the guide-plates projects a stud, a, to which the spiral spring D, that forms the connection of the base and seat frames, is applied in the usual manner. The upper end of the spring D is hung to a similar projecting stud, b, of the connectingarm E of the seat-frame, which arm is attached by its enlarged upper end securely to the rockers. The lower part of the arm E is extended down ward between the hook-shaped terminals of the guide-plate O, and provided immediately below the enlarged upper part with a solid cheek, d, of U shape, the convex sides of which slide along the upper surface of the hook-shaped ends of the guide-plate O.

The lower part of the arm swings in the space between the arms of the guide-plate, but is slightly curved, so as to be a short distance from the rail, for the purpose of providing the required space for a pin or stud, c, that projects from the lower end of the arm toward the rail. Arubber roller or sleeve, f, is placed on the pin, for serving as a cushion and making the contact with the hook noiseless. The rubber sleeve f is retained in position on the pin by the arm and rail, and cannot play loose therefrom by the working of the chair.

As the arm E is guided by its check, as well as by the stop-pin, along the guide-plate during the motion of the rocker in either direction, it cannot get locked nor get out of order, forming thereby a very reliable attachment to the chair, by which no recessing of the base is required, the rocking-chair being ready for use as soon as the guide-plate, arm, and con-.

nectin g-sprin g are applied thereto. Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The combination of the curved guide-plate (J, provided with hook ends, that is secured to the base-frame below the top of the rail, with a connecting-spring, D, and a swinging arm, E, of the seat-frame, said arm having a solid cheek, d, that enters between the hook ends, and a stop pin or stud that projects from the lower end of the arm'toward the rail, so that the cushioning-sleeve is securely retained between the rail and arm, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 7th day of May, 1879.

WILLIAM LIESENBEIN.
